Hi again pammeiann47,
Thanks for your patience!
You have described to me a 9 yr old female Greyhound who has a scrape over her cannon bones on her right rear leg. She licks at the wound which impairs healing, but panics when a Bite Not collar is applied.
There are a number of options here to help this wound to heal. Let me go over the issues I would like to discuss:
1. Wound care
In order to promote healing, the most helpful thing would be for you to wash the wound with warm water and antibacterial soap 3 times daily for 3 days, then twice daily for 2 days. If you have antibacterial soap in the house (Hibitane or chlorhexidene soap would be ideal, hand soap is ok if you have nothing else) you can add about a tablespoon to a cup of warm water.
Put a washcloth in, then wring it out. Gently scrub the wound for about 10 minutes to try to remove any discharge from it and keep it clean. Wipe the area with a plain wet washcloth and pat dry.
You can apply a thin layer of antibiotic ointment (such as BNP ointment) to the wound after cleaning it.
2. Prevent her from licking it
You are absolutely right that is not going to heal if she licks it! So, either she wears the Bite Not collar and you give her something to ease her anxiety (I'll come back to this) or the wound has to be covered.
a) Covering it
Your veterinarian could certainly apply a bandage to the wound to keep her away from it. Bandages can be sprayed with Bitter Apple spray to keep dogs from chewing on them. Here is what I mean: http://www.bitterapple.com/
Alternatively, you could try getting a long cotton sock and putting that over the wound. You can anchor it by putting some strips of tape at the top. I would recommend strips that go up and down the leg, NOT around it as you can cut off circulation if you encircle the leg tightly. Again, you could spray with Bitter Apple. This sock could be removed when you are around to monitor her, if she will listen when you ask her to leave the wound alone
b) Using the Bite Not collar
It does sound as though this collar terrifies her, poor girl! I wonder if she would tolerate it better if you did not use the part that goes under her body?
Anyway, if you are forced to use this, you might have to relax her a bit. Without taking her to a vet, you are right that you can use BENADRYL (diphenhydramine). The dose that one generally gives is 1mg/lb. It comes as 25 mg tablets, thus your dog could safely have 2.5 tablets! Naturally, you don't have to give that much if you find a smaller dose is effective.
Here is more about Benadryl:
Benadryl causes sedation in most dogs it is given to – but excitement in the very occasional dog!
Another option would be to try Composure Liquid from Vetri Science It is composed of a protein extract from a milk product and a soy product plus a few other things. It seems to work great for many dogs and cats. http://www.vetriscience.com/composure-liquid.php
If your dog went to see a vet, then the vet could prescribe stronger sedatives for you to give at home, such as acepromazine. This is a sedative that can be given either by injection (in the clinic) or by pills (which you could give at home). It has much more of a sedating effect than the Benadryl. But it also has more serious side effects such as low blood pressure, so a vet has to examine a patient before giving it.
Here are some more ideas: http://www.petplace.com/dogs/stop-it-how-to-stop-your-dog-from-licking/page1.aspx
I do hope that these ideas help you to help your dog. If the wound is looking infected (has an odor, discharge, redness, swelling or pain) then do see your veterinarian promptly to get antibiotics for your dog. Your veterinarian could also bandage the wound so she couldn't get at it.
I hope that this helps you to help your Greyhound!
